ARTHUR B. CARROLL, OF BALTIMORE, MARYLAND, ASSIGNOR TO BAUM- GARTEN AND COMPANY, OF BALTIMORE, MARYLAND, A FIRM.

PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent N 0. 716,624, dated December 23, 1902.

Applioation filed March 24. 1902. Serial No. 99,559- (No model.)

To ctZZ whom it may concern:

Be it known that I, ARTHUR B. CARROLL, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Printing-Presses, of which the following is a specification.

This invention relates to printing-presses, particularly to that class of presses provided with a platen mounted to rock toward and from a stationary bed over which an oscillating inking-roller is moved.

The invention consists of certain improvements in the mechanism for rocking the platen and oscillating the inking-roller, as hereinafter fully described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of the printingpress, illustrating two different positions of the parts in full lines and dotted lines, respectively; and Fig. 2 is a rear elevation thereof.

Referring to the drawings, the letter a designates the base of the press, and b designates a standard rising from said base and which supports the stationary bed A and its curved inking-roller guides c, and on the upper end of said standard is mounted the rotary inking-plate d, provided on its under surface with the usual pawl-engaged teeth 61'.

The letter B designates the platen of the press, pivoted at its lower end to rock toward and from the stationary bed A.

The standard Z) is provided on its rear side with a tubular boss I), in which a shaftfis mounted to rotate, and said shaft is provided at each end with a crank f, which cranks are connected to the sides of the platen by rods g. A handle It is secured to one of said cranks, whereby to rotate the shaft f and rock the platen B toward and from the bed A. Mounted to partially turn on said shaft f is a tubular spindle 1:, provided with a portion 0L, bridging said boss I), and rigidly secured to said spindle are two frames j, in which are mounted sliding spring-pressed gripping-rods it, each provided at one end with a hook 7c,

intended to take over one end of the spindle Z of an inking-roller Z. The said roller is provided at each end with an antifriction-ring Z adapted to roll along the curved guides c.

In order to oscillate the inking-roller Z over the stationary bed A and over the inkingplate d, one of the frames j is connected by a link 'm to one of the connecting-rods g intermediate of the ends of the latter, and in order to intermittently turn the inking-plate 01, so that it will present different portions of its inked surface to the inking-roller, a rocking pawl 77. is provided, said pawl being carried by an arm a on the tubular spindle i.

In practice the handle 71. is revolved, which rocks the platen B toward and from the stationary bed A, and at the same time the link m, connected to one of the rods g, partially rotates the tubular spindle 7) back and forth, thereby carrying the inking-roller down over the type-form on the bed A as the platen is moved away from the latter and then carrying the said roller up over the inking-plate.

The press herein shown and described is particularly designed as a toy press for printing small articles, such as calling-cards and the like.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A printing-press, comprising a standard; a bed supported on said standard; a platen mounted to rock toward and from said bed; a rotary shaft supported by said standard and provided at each end with a crank; rods connecting said cranks with said platen; a tubular spindle mounted to partially rotate on said shaft; two frames secured rigidly to said tu- ARTHUR B. CARROLL.
